  1. 21. Collaborative Localization and Mapping with Heterogeneous Depth Sensors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Villagrá Guilarte; [2020]
    Nyckelord :;

    Sammanfattning : Simultaneous Localization and Mapping (SLAM) is the process in which a robot and other devices navigate in environments by simultaneously building a map of the surroundings and localizing itself within it. SLAM for single agents and specific sensors has matured during these last two decades. LÄS MER

  3. 22. Optimization of Acquisition Time for 177- Lu SPECT with Two Energy Windows

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Fanny Mörnsjö Centofanti; [2019]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background & Aim: The imaging process following the treatment of 177Lu-DOTATATE is in some medical clinics demanding on both patients and the clinic. Usually a number of images are acquired, with different time intervals to the time of injection. LÄS MER

  4. 23. Normalized Convolution Network and Dataset Generation for Refining Stereo Disparity Maps

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Daniel Cranston; Filip Skarfelt; [2019]
    Nyckelord :Disparity Map; Disparity Refinement; Dataset Generation; Neural Network; Normalized Convolution;

    Sammanfattning : Finding disparity maps between stereo images is a well studied topic within computer vision. While both classical and machine learning approaches exist in the literature, they frequently struggle to correctly solve the disparity in regions with low texture, sharp edges or occlusions.

  5. 24. Map Matching to road segments using Hidden Markov Model with GNSS, Odometer and Gyroscope

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Hugo Lindholm; [2019]
    Nyckelord :map matching; hmm; hidden markov model; gnss;

    Sammanfattning : In this thesis the Hidden Markov Model (HMM) is used in the process of map matching to investigate the accuracy for road segment map matching. A few HMM algorithms using a Global Navigation Satellite System (GNSS) receiver, odometer and gyroscope sensors are presented. The HMM algorithms are evaluated on four accuracy metrics. LÄS MER

  7. 25. Improving movie recommendations through social media matching

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Roman Kuroptev; Anton Lagerlöf; [2019]
    Nyckelord :Twitter; Collaborative filtering; Recommender systems; LSI; Top k; Social-matching;

    Sammanfattning : Rekommendationssystem är idag väsentliga för att navigera den enorma mängd produkter tillgängliga via internet. Då social media i form av Twitter vid tidigare tillfällen använts för att generera filmrekommendationer har detta främst varit för att hantera cold-start, ett vanligt drabbande problem för collaborative-filtering.
